4 mid range PSUs compared

post #1 of 20
Thread Starter 
So i am a bit bored so i tought hey why not compare 4 mid range PSU´s to each other and see which one does best

Units picked for this is the

Rosewill Capstone
Seasonic G
Corsair RM
Cooler Master VS

First of is voltage regulation

Lets start with the Seasonic G





Next is the Rosewill Capstone





Corsair RM





Cooler Master VS





Next is ripple

Again Seasonic G



Rosewill Capstone



Corsair RM


Cooler Master VS


Next up is fans in the 4 units

So lets start with the fan in the Seasonic G



120 mm Double Ball-Bearing Fan

The cooling fan is provided by ADDA and its model number is AD1212MB-A70GL (120mm, 12V, 0.33 A, 2050 RPM max). It uses ball bearings and can be expected to have a longer lifespan than a sleeved-bearing fan.

Nexi is the Rosewill Capstone

140 mm Double Ball Bearing Fan



The cooling fan wears Rosewill's logo but its model number (RL4ZB1402512M) reveals that it is actually made by Globe Fan. It uses ball bearings, so it has an extended lifetime compared to a sleeved bearings one and it can reach up to 1200RPM with 24.9dBA max noise output, so it is considered a quiet fan.

Next is the Corsair RM

135 mm Rifle-Bearing Fan (NR135L)



The fan is the same as the one in the RM750/850 units. It operation is silent at even full speed, and it uses rifle bearings, an enhanced type of the plain sleeve bearings. As you can see from the photos above, its model number is NR135L (12 V, 0.22 A). Finally, the fan profile is thankfully less relaxed than that of the RM750/850 units, which then puts less stress on heat-sensitive components like electorlytic caps.

Next is the Cooler Master VS

120 mm Double Ball-Bearing Fan (D12BH-12)



The fan is provided by Yate Loon and uses double ball-bearings to increase its lifetime. This fan is really strong, and we definitely didn't expect to see one in a Gold-certified PSU of medium capacity, but it is restricted to very low speeds most of the time since energy dissipation is also very low. The fan's model number is D12BH-12 (12 V, 2300 RPM, 89 CFM, 41 dBA).

Cooler Master VS takes a clear win in voltage regulation which means its the most stable of the 4

Seasonic G wins ripple which means it give the most clean power of the 4

Bigest loser ripple wise is the Corsair RM

Bigest loser voltage regulation wise is the Rosewill Capstone

Fan quality wise the Cooler Master VS seems like the winner

If we compare fan quality with ripple and voltage regulation and then price the Cooler Master VS seems like the overall winner with the Seasonic G a close second


Note that price change all the time so i am talking about the price as it was at the time this thread was made and not the price when you read this or if one of the units is on sale

That cooler master V is nice, it has about same voltage regulation as AX1200i and EVGA Supernova 1300w?

Thats the Cooler Master VS not the V

The V and VS have zero in common with each other

VS is upper mid range the V is high end

Bah, the inclusion of one little letter totally changes the PSU? it's confusing sometimes.

Especially with AX1200i.... look at that "i" you can barely see it at all, but it's a different psu, not the old 2+ years old model.

Well it is called the V450S/550S/650S/750S

But Corsair also has a VS series Two Cables already have problems with messing them up
